Summary of Field Work: |
The focus is on Lamon Bay, along the east coast of Luzon. The continental configuration of Lamon Bay is quite complex: from the Catanduanes Island (which forms the northern boundary of San Bernardino Strait) the continental margin runs east-west, with an irregular coastline, a wide shelf of spotted with many coral reefs and rich fishing grounds. At the western end is Polillo Island, where interesting ocean color features have been noted. North of Polillo the shelf runs north-south and narrows substantially, with the steep drop into the deep ocean within 10 km of the coast. The ocean depths in Lamon Bay reach to over 5000 m. While all of the collaborative team will be involved with all aspects of the program, the Philippines researchers will focus on the marine ecosystem issues, and Flament will focus on the surface layer circulation features as revealed by the HF Radar system and shelf-slope mooring time series along the southern tier of Lamon Bay, and Gordon covers the hydrographic component as required to investigate the stratification and circulations of Lamon Bay, with emphasis on shelf/slope interactions, including a pair of moorings to obtain a time series of shelf/slope exchange in the anomalously narrow continental margin regime, where the Kuroshio is first clearly recognizable. We envision two cruises from a UNOLS vessel: one in Feb 2011 and another in Feb 2012. Each would be 15 days long, Manila to Manila. Instrumented moorings will be set out on the first and recovered on the second. A july-sept cruise 2011 from a Philippine ship will be done, typhoon allowing, in the Polillo box.
The entire ship track plan will first be rapidly covered with the UNOLS vessel underway system (T, S, Chl-a, hull ADCP), without stations, to gain a quasi-stationary image of the surface water properties and of the water column currents. The track lines will allow for underway data mapping as well as critically needed bottom bathymetry data to better define the role of the marine morphology in forming the details of the circulation/stratification. The ship will then deploy the 4 to 6 shallow water moorings designed to provide time series information of currents and bottom water properties of the upper slope and shelf regimes. A second full run of the track line will be made with CTD stations The CTD stations provide a view of the T/S/Oxy water column profile as well as allow for the collection of water samples for chem/ bio analysis, to be carried out by the Philippine researchers. |

Summary of Facility Requirements: |
Ship CTD and water sampling bottles.
Ship underway system for sea surface temperature, salinity, chlorophyll-a ocean currents in upper ~300 m.
Mooring deployment: upward looking ADCP, little vertical wire extent. |

Repeating Cruise?

No |

Description of Repeating cruise requirements: |
A repeat cruise in the mid-April to mid-June 2012 time frame will be requested. During that time we repeat the CTD stations and recover the ADCP moorings. Same ship time requested as for the 2011 cruise. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
May 2011 would allow us to measure the net result of the winter monsoon effect on Lamon Bay. There will be minimum conflict with Typhoon activity, when the ship may be drawn into a Typhoon response program. |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
The US material will be loaded in Kaohsiung, as Manila is not ideal with shipping to/from, and the port system is not efficient. However as their is a large group of researchers from the Philippines who will participate in the Lamon Bay work, we request a personal pick-up and after the Lamon Bay work, a personnel drop off in Manila. One day in Manila for pickup and 1 day for drop off should be sufficient [touch/go].
The Philippine group will bring onto the ship some lab equipment [nothing large that requires a crane]. The transit time requested is from Manila to Lamon Bay, ~ 1 days, and the ~ 1 day return to Manila. The Kaohsiung to Manila would be transit time. If that needs to be added to my ship request, then one would have to add 4 days transit Kaohsiung to Manila. Not sure how to handle the end of the cruise- the US group will not ship out of Manila, but will wait for the ships next stop as a more efficient port [Kaohsiung again?]. |
